Description
Technical Field
[0001] This utility model belongs to the technical field of grinding devices, specifically relating to a device for ultra-fine grinding and reuse of garlic powder. Background Technology
[0002] Minced garlic, a common form of primary garlic processing, is widely used in the food industry, including condiments, pickled products, and dietary supplements. During processes such as garlic paste preparation, pre-cooked garlic products, and garlic oil extraction, primary garlic residue with larger particle sizes and impurities is often generated. Directly discarding this garlic residue, due to its uneven particle size or high impurity content, not only wastes resources but may also cause environmental problems such as odor pollution. Therefore, it is necessary to effectively reprocess this garlic residue into finer, purer, reusable garlic powder, which can be used as an ingredient in animal feed or as a condiment.
[0003] Since residual garlic generally contains a certain amount of moisture, if it enters the grinding mechanism directly without pre-drying treatment, it is very easy to form an adhesive layer on the surface of the grinding disc. This not only reduces the grinding efficiency but may also cause the disc to slip. Furthermore, existing devices generally grind the garlic directly. Due to the lack of pre-crushing, the garlic particles are relatively large, resulting in low grinding efficiency and affecting production efficiency. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a garlic mincing ultrafine grinding and reuse device that can achieve preliminary dehydration and drying during the feeding process, significantly improving the subsequent grinding efficiency, preventing material sticking or blade slippage due to excessive moisture, and simultaneously performing coarse crushing and ultrafine grinding of garlic mincing. This allows the garlic mincing to be fully crushed before grinding, and the crushing and grinding are carried out in a staggered manner. In the continuous processing of large batches of materials, while one batch of garlic mincing is being crushed, the previous batch of garlic mincing can be ground at the same time, reducing the grinding time required and effectively improving grinding production efficiency and product uniformity.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a garlic ultrafine grinding and reuse device, comprising a frame, a coarse crushing device and a micro grinding device mounted on the top of the frame, the coarse crushing device comprising a first support mounted on the top of the frame, a coarse crushing chamber mounted on the top side of the first support, a first filter screen fixedly mounted inside the coarse crushing chamber and a coarse crushing blade mounted rotatably, the micro grinding device comprising a second support mounted on the top of the frame, a grinding chamber mounted on the top of the second support, a second filter screen fixedly mounted inside the grinding chamber and a grinding blade mounted rotatably, one end of the rotating shaft of each of the coarse crushing blade and the grinding blade being connected to a set of drive mechanisms, the bottom of the grinding chamber being connected to a discharge pipe, the top of the coarse crushing chamber being connected to a cyclone separator, an air inlet and feed pipe connected to one side of the top of the cyclone separator, a fan connected to one end of the air inlet and feed pipe, a first spiral elevator connected to the lower middle section of the air inlet and feed pipe, a second spiral elevator connected between the coarse crushing chamber and the grinding chamber, and a heating and drying device provided on the outside of the first spiral elevator.
[0006] The beneficial effects of this utility model are as follows: large-particle garlic mince that has undergone preliminary treatment is fed into the feed hopper. The garlic mince slides down into the bottom of the lifting cylinder of the first screw elevator under the action of gravity. The second motor drives the internal spiral blade conveying shaft to rotate, causing the garlic mince to spiral upward along the lifting cylinder. During the upward conveying of the garlic mince along the lifting cylinder of the first screw elevator, the electric heating wire arranged inside the external heating jacket runs to heat the lifting cylinder. The heat is conducted through the cylinder to the garlic mince inside, causing the garlic mince to gradually heat up during the upward process, drying the moisture. The moisture is discharged through the vent and blocked by the internal filter screen to prevent leakage. This step achieves efficient material conveying on the one hand and preliminary dehydration and drying on the other hand, significantly improving the subsequent grinding efficiency and preventing material sticking or blade slippage due to excessive moisture.
[0007] After drying, the minced garlic is lifted and conveyed to the middle section of the air inlet and feed pipe. The fan operates to input high-speed airflow into the air inlet and feed pipe. The minced garlic is sent into the cone of the cyclone separator along with the high-speed airflow. The airflow generates strong rotation inside the cone, forming a downward outer vortex. Under the action of centrifugal force, the minced garlic rotates and settles to the bottom along the wall. The vortex shroud physically blocks and guides the flow, destroying the formation of the bottom vortex, which plays a role in suppressing the bottom vortex and reducing the back mixing of the material settling to the bottom. At the same time, it reduces pressure loss. The outer vortex turns to the center at the bottom of the cone, forming an upward inner vortex. Lighter impurities such as garlic skin and roots rise to the top with the upward inner vortex and are discharged through the exhaust pipe into the connected debris collection bag, realizing the separation of light impurities mixed in with the minced garlic, improving the purity of the minced garlic and the quality of subsequent processing.
[0008] By using a coarse crushing and ultrafine grinding device that can operate synchronously, along with an automatic conveying mechanism between the two, this device can simultaneously perform coarse crushing and ultrafine grinding of garlic mince. This allows the garlic mince to be fully crushed before grinding, and the crushing and grinding are carried out in a staggered manner. In the continuous processing of a large batch of materials, while one batch of garlic mince is being crushed, the previous batch of garlic mince that has been crushed can be ground at the same time, reducing the grinding time required and effectively improving grinding production efficiency and product uniformity.
[0009] In order to clean the residual material in the coarse crushing chamber and grinding chamber:
[0010] As a further improvement to the above technical solution: one end of the coarse crushing chamber is connected to a first side cover plate, and one end of the grinding chamber is connected to a second side cover plate.
[0011] The beneficial effects of this improvement are: by opening the first side cover and the second side cover, the residual material in the coarse crushing chamber and the grinding chamber can be cleaned.
[0012] To coarsely chop the garlic:
[0013] As a further improvement to the above technical solution: a plurality of crushing blades are fixedly arranged in a ring on one side of the coarse crushing disc, and auxiliary striking rods are provided on both the side of the first side cover plate near the interior of the coarse crushing chamber and the side of the coarse crushing disc.
[0014] The beneficial effects of this improvement are as follows: when the coarse crushing disc rotates at high speed, the multiple crushing blades arranged on its side work in coordination with the auxiliary striking rods fixed on the first side cover and the coarse crushing disc during the rotation process to perform high-speed cutting, impact and stirring crushing of garlic mince, quickly breaking up large particles and achieving primary crushing.
[0015] To grind the garlic:
[0016] As a further improvement to the above technical solution: a plurality of rotating grinding blades are fixedly arranged in a ring on one side of the grinding disc, and a plurality of fixed grinding blades are fixedly arranged inside the second filter screen. The surfaces of the rotating grinding blades and the fixed grinding blades are all provided with uniformly arranged grinding teeth.
[0017] The beneficial effects of this improvement are as follows: Several rotating grinding blades are installed on one side of the grinding disc, and their blade surfaces are arranged with uniform grinding teeth. They mesh with multiple fixed grinding blades fixed inside the second filter screen to form multiple sets of moving and stationary blade gaps. When the grinding disc rotates at high speed, the garlic mince is repeatedly sheared and ground between the rotating grinding blades and the fixed grinding blades, and broken into ultrafine particles.
[0018] To drive the coarse crushing cutter head and grinding cutter head to rotate at high speed:
[0019] As a further improvement to the above technical solution: the drive mechanism includes a first pulley connected to the rotating shaft of the coarse crushing cutter disc and the grinding cutter disc, the first pulley being connected to a second pulley via a belt, the second pulley being fixed to the output end of a first motor, and the first motor being fixed to the top of the frame.
[0020] The beneficial effects of this improvement are as follows: the first motor at the top of the frame drives the second pulley to rotate, and the second pulley drives the first pulley to rotate via a belt, thereby driving the coarse crushing cutter head and the grinding cutter head to rotate at high speed.
[0021] To separate the light impurities mixed in with the minced garlic:
[0022] As a further improvement to the above technical solution: the cyclone separator includes a cone body connected to the feed inlet of the coarse crushing chamber, an exhaust pipe is installed through the top of the cone body, a vortex shroud is provided on the inner side of the bottom of the cone body, an air inlet and feed pipe is connected to the top side of the cone body, and a debris collection bag is connected to the end of the exhaust pipe.
[0023] The beneficial effects of this improvement are as follows: The fan operation introduces high-speed airflow into the inlet and feed pipes. Garlic mince is sent into the cone of the cyclone separator along with the high-speed airflow. The airflow generates strong rotation inside the cone, forming a downward outer vortex. Under the action of centrifugal force, the garlic mince adheres to the wall, rotates, and settles to the bottom. The vortex shroud, through physical obstruction and flow guidance, disrupts the formation of the bottom vortex, thereby suppressing the bottom vortex and reducing back-mixing of materials settling to the bottom. At the same time, it reduces pressure loss. The outer vortex turns to the center at the bottom of the cone, forming an upward inner vortex. Lighter impurities such as garlic peel and roots rise to the top with the upward inner vortex and are discharged through the exhaust pipe, entering the connected debris collection bag. This achieves the separation of light impurities mixed in with the garlic mince, improving the purity of the garlic mince and the quality of subsequent processing. The garlic mince separated from the impurities is introduced into the coarse crushing chamber from the bottom of the cyclone separator.
[0024] As a further improvement to the above technical solution: the feed inlet of the first screw conveyor is connected to the feed hopper, the bottom discharge outlet of the coarse crushing chamber is connected to the feed inlet of the second screw conveyor, and the discharge outlet of the second screw conveyor is connected to the top of the grinding chamber.
[0025] In actual use, the operator first puts the pre-processed large-particle garlic into the feed hopper. The garlic falls into the bottom of the lifting cylinder of the first screw conveyor under the action of gravity. The first screw conveyor lifts the garlic into the air inlet and feed pipe and enters the cyclone separator with the airflow, realizing the automatic feeding of this device. The garlic after coarse crushing in the coarse crushing bin enters the second screw conveyor. The second screw conveyor lifts the garlic inside and discharges it into the grinding bin for grinding.
[0026] To lift and transport the minced garlic:
[0027] As a further improvement to the above technical solution: both the first spiral elevator and the second spiral elevator include a lifting cylinder, the bottom end of which is connected to a second motor, and the output end of the second motor is connected to a spiral blade conveying shaft that is rotatably installed inside the lifting cylinder.
[0028] The beneficial effects of this improvement are as follows: the internal spiral blade conveying shaft is driven to rotate by the second motor, and after the minced garlic enters the lifting cylinder, the minced garlic is driven to spiral upward along the lifting cylinder body by the spiral blade conveying shaft.
[0029] To dry the minced garlic before grinding:
[0030] As a further improvement to the above technical solution: the heating and drying device includes an outer heating sleeve installed on the outside of the lifting cylinder of the first spiral elevator, an electric heating wire is provided inside the outer heating sleeve, a dehumidification port is provided between the inner and outer sides of the lifting cylinder of the first spiral elevator, and a filter screen is fixedly provided inside the dehumidification port.
[0031] The beneficial effects of this improvement are as follows: During the upward conveying of minced garlic along the lifting cylinder of the first spiral elevator, the electric heating wire arranged inside the outer heating jacket operates to heat the lifting cylinder. The heat is conducted through the cylinder body to the minced garlic inside, causing the minced garlic to gradually heat up during the ascent, drying the moisture. The moisture is discharged through the vent and blocked by the internal filter screen to prevent leakage. This step achieves efficient material conveying on the one hand, and preliminary dehydration and drying on the other hand, significantly improving the efficiency of subsequent grinding and preventing material sticking or blade slippage due to excessive moisture.

[0040] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0041] like Figure 1-6 As shown, a garlic ultrafine grinding and recycling device includes a frame 1. A coarse crushing device 2 and a micro-grinding device 3 are mounted on the top of the frame 1. The coarse crushing device 2 includes a first support 4 mounted on the top of the frame 1. A coarse crushing chamber 5 is mounted on the top side of the first support 4. A first filter screen 6 is fixedly installed inside the coarse crushing chamber 5, and a coarse crushing blade 7 is rotatably mounted thereon. The micro-grinding device 3 includes a second support 12 mounted on the top of the frame 1. A grinding chamber 13 is mounted on the top of the second support 12. A second filter screen 14 is fixedly installed inside the grinding chamber 13, and a grinding blade is rotatably mounted thereon. The coarse crushing disc 7 and the grinding disc 15 are each connected to a set of drive mechanisms 19 at one end of their rotating shafts. The bottom of the grinding chamber 13 is connected to the discharge pipe 24. The top of the coarse crushing chamber 5 is connected to the cyclone separator 25. An air inlet and feed pipe 29 is connected to one side of the top of the cyclone separator 25. A fan 30 is connected to one end of the air inlet and feed pipe 29. A first spiral elevator 31 is connected to the lower middle section of the air inlet and feed pipe 29. A second spiral elevator 33 is connected between the coarse crushing chamber 5 and the grinding chamber 13. A heating and drying device is provided on the outside of the first spiral elevator 31.
[0042] Large, pre-processed garlic granules are fed into the feed hopper 32. Under gravity, the garlic granules slide down into the bottom of the lifting cylinder 34 of the first screw conveyor 31. The second motor 35 drives the internal spiral blade conveying shaft 36 to rotate, causing the garlic granules to spiral upward along the cylinder 34. During the upward conveying of the garlic granules along the lifting cylinder 34 of the first screw conveyor 31, the electric heating wires 38 arranged inside the outer heating jacket 37 operate to heat the lifting cylinder 34. The heat is conducted through the cylinder 34 to the garlic granules inside, causing the garlic granules to gradually heat up during the upward process and dry the moisture. The moisture is discharged through the vent 39 and blocked by the internal filter screen 40 to prevent leakage. This step achieves efficient material conveying and preliminary dehydration and drying, significantly improving the efficiency of subsequent grinding and preventing material sticking or blade slippage due to excessive moisture.
[0043] After drying, the minced garlic is lifted and conveyed to the middle section of the air inlet and feed pipe 29. The blower 30 operates to input high-speed airflow into the air inlet and feed pipe 29. The minced garlic is sent into the cone body 26 of the cyclone separator 25 along with the high-speed airflow. The airflow generates strong rotation inside the cone body 26, forming a downward outer vortex. Under the action of centrifugal force, the minced garlic rotates and sinks to the bottom. The vortex shroud 28 physically blocks and guides the flow, destroying the formation of the bottom vortex, which plays a role in suppressing the bottom vortex and reducing the back mixing of the material settling to the bottom, while reducing pressure loss. The outer vortex turns to the center at the bottom of the cone body 26, forming an upward inner vortex. Lighter impurities such as garlic skin and roots rise to the top with the upward inner vortex and are discharged by the exhaust pipe 27, entering the connected debris collection bag 41, realizing the separation of light impurities mixed in with the minced garlic, improving the purity of the minced garlic and the quality of subsequent processing.
[0044] By using a coarse crushing and ultrafine grinding device that can operate synchronously, along with an automatic conveying mechanism between the two, this device can simultaneously perform coarse crushing and ultrafine grinding of garlic mince. This allows the garlic mince to be fully crushed before grinding, and the crushing and grinding are carried out in a staggered manner. In the continuous processing of a large batch of materials, while one batch of garlic mince is being crushed, the previous batch of garlic mince that has been crushed can be ground at the same time, reducing the grinding time required and effectively improving grinding production efficiency and product uniformity.
[0045] One end of the coarse crushing chamber 5 is connected to a first side cover plate 10, and one end of the grinding chamber 13 is connected to a second side cover plate 18.
[0046] By opening the first side cover 10 and the second side cover 18, the remaining material in the coarse crushing chamber 5 and the grinding chamber 13 can be cleaned.
[0047] A plurality of crushing blades 8 are fixedly arranged in a ring on one side of the coarse crushing disc 7, and auxiliary striking rods 9 are provided on both the side of the first side cover plate 10 near the interior of the coarse crushing chamber 5 and the side of the coarse crushing disc 7.
[0048] When the coarse crushing disc 7 rotates at high speed, multiple crushing blades 8 arranged on its side work in conjunction with the auxiliary striking rods 9 fixed on the first side cover plate 10 and the coarse crushing disc 7 during the rotation process to perform high-speed cutting, impact and stirring crushing of garlic mince, quickly breaking up large particles and achieving primary crushing.
[0049] A plurality of rotating grinding blades 16 arranged in a ring are fixed on one side of the grinding disc 15, and a plurality of fixed grinding blades 17 are fixed inside the second filter screen 14. The surfaces of the rotating grinding blades 16 and the fixed grinding blades 17 are provided with uniformly arranged grinding teeth.
[0050] Several rotating grinding blades 16 are installed on one side of the grinding disc 15. The blades have uniform grinding teeth and mesh with multiple fixed grinding blades 17 fixed inside the second filter screen 14 to form multiple sets of moving and stationary blade gaps. When the grinding disc 15 rotates at high speed, the garlic mince is repeatedly sheared and ground between the rotating grinding blades 16 and the fixed grinding blades 17, and broken into ultra-fine particles.
[0051] The drive mechanism 19 includes a first pulley 20 connected to the rotating shaft of the coarse crushing disc 7 and the grinding disc 15. The first pulley 20 is connected to a second pulley 22 via a belt 21. The second pulley 22 is fixed to the output end of a first motor 23. The first motor 23 is fixed to the top of the frame 1.
[0052] The first motor 23 at the top of the frame 1 drives the second pulley 22 to rotate, and the second pulley 22 drives the first pulley 20 to rotate through the belt 21, thereby driving the coarse crushing cutter disc 7 and the grinding cutter disc 15 to rotate at high speed.
[0053] The cyclone separator 25 includes a cone body 26 connected to the feed inlet of the coarse crushing chamber 5. An exhaust pipe 27 is installed through the top of the cone body 26. A vortex shroud 28 is provided on the inner side of the bottom of the cone body 26. An air inlet and feed pipe 29 is connected to one side of the top of the cone body 26. A debris collection bag 41 is connected to the end of the exhaust pipe 27.
[0054] The blower 30 operates to input high-speed airflow into the inlet and feed pipe 29. Garlic mince, along with the high-speed airflow, is sent into the cone 26 of the cyclone separator 25. The airflow generates strong rotation inside the cone 26, forming a downward outer vortex. Under the action of centrifugal force, the garlic mince rotates and settles to the bottom. The vortex shroud 28, through physical blocking and guiding, disrupts the formation of the bottom vortex, thereby suppressing the bottom vortex and reducing back-mixing of materials settling to the bottom, while also reducing pressure loss. The outer vortex turns to the center at the bottom of the cone 26, forming an upward inner vortex. Lighter impurities such as garlic skin and roots rise to the top with the upward inner vortex and are discharged through the exhaust pipe 27, entering the connected debris collection bag 41. This achieves the separation of light impurities mixed in with the garlic mince, improving the purity of the garlic mince and the quality of subsequent processing. The garlic mince separated from the impurities is introduced into the coarse crushing chamber 5 from the bottom of the cyclone separator 25.
[0055] The feed inlet of the first spiral elevator 31 is connected to the feed hopper 32, the bottom discharge outlet of the coarse crushing chamber 5 is connected to the feed inlet of the second spiral elevator 33, and the discharge outlet of the second spiral elevator 33 is connected to the top of the grinding chamber 13.
[0056] In actual use, the operator first puts the pre-processed large-particle garlic into the feed hopper 32. The garlic falls into the bottom of the lifting cylinder 34 of the first screw elevator 31 under the action of gravity. The first screw elevator 31 lifts the garlic into the air inlet and feed pipe 29 and enters the cyclone separator 25 with the airflow, realizing the automatic feeding of this device. The garlic after coarse crushing in the coarse crushing bin 5 enters the second screw elevator 33. The second screw elevator 33 lifts the garlic inside and discharges it into the grinding bin 13 for grinding.
[0057] Both the first spiral elevator 31 and the second spiral elevator 33 include an elevator cylinder 34. The bottom end of the elevator cylinder 34 is connected to a second motor 35. The output end of the second motor 35 is connected to a spiral blade conveying shaft 36 that is rotatably installed inside the elevator cylinder 34.
[0058] The second motor 35 drives the internal spiral blade conveying shaft 36 to rotate. After the minced garlic enters the lifting cylinder 34, the spiral blade conveying shaft 36 drives the minced garlic to spirally rise along the cylinder body of the lifting cylinder 34.
[0059] The heating and drying device includes an outer heating sleeve 37 installed on the outside of the lifting cylinder 34 of the first spiral elevator 31. An electric heating wire 38 is provided inside the outer heating sleeve 37. A dehumidification port 39 is provided between the inner and outer sides of the lifting cylinder 34 of the first spiral elevator 31. A filter screen 40 is fixedly provided inside the dehumidification port 39.
[0060] As the minced garlic is conveyed upward along the lifting cylinder 34 of the first spiral elevator 31, the electric heating wire 38 arranged inside the outer heating jacket 37 operates to heat the lifting cylinder 34. The heat is conducted through the cylinder body of the lifting cylinder 34 to the minced garlic inside, causing the minced garlic to gradually heat up during the ascent, drying the moisture. The moisture is discharged through the vent 39 and blocked by the internal filter screen 40 to prevent leakage. This step achieves efficient material conveying and preliminary dehydration and drying, significantly improving the efficiency of subsequent grinding and preventing material sticking or blade slippage due to excessive moisture.
[0061] The working principle and usage process of this utility model are as follows: In actual use, the operator first puts the pre-processed large-particle garlic into the feed hopper 32. The garlic falls into the bottom of the lifting cylinder 34 of the first screw elevator 31 under the action of gravity. The second motor 35 drives the internal spiral blade conveying shaft 36 to rotate, causing the garlic to spiral upward along the cylinder 34. During the upward conveying of the garlic along the lifting cylinder 34 of the first screw elevator 31, the electric heating wire 38 arranged inside the outer heating jacket 37 operates to heat the lifting cylinder 34. The heat is conducted to the garlic inside the cylinder 34, causing the garlic to gradually heat up during the upward process, drying the moisture. The moisture is discharged through the vent 39 and then through the internal... The filter screen 40 of the section blocks the minced garlic to prevent leakage. This step achieves efficient material conveying and preliminary dehydration and drying, significantly improving subsequent grinding efficiency and preventing material sticking or blade slippage due to excessive moisture. The dried minced garlic is then lifted and conveyed to the middle section of the air inlet and feed pipe 29. The blower 30 operates to input high-speed airflow into the air inlet and feed pipe 29. The minced garlic, along with the high-speed airflow, is sent into the cone 26 of the cyclone separator 25. The airflow generates strong rotation inside the cone 26, forming a downward outward vortex. Under the action of centrifugal force, the minced garlic adheres to the wall, rotates, and settles to the bottom. The vortex shroud 28, through physical blocking and guiding, disrupts the formation of the bottom vortex, thereby suppressing the bottom vortex and reducing the amount of garlic settling to the bottom. The material back-mixing effect reduces pressure loss. The outer swirling flow turns towards the center at the bottom of the cone 26, forming an upward inner swirling flow. Lighter impurities such as garlic peels and roots rise to the top with the upward inner swirling flow and are discharged through the exhaust pipe 27, entering the connected debris collection bag 41. This separates the light impurities mixed in with the garlic mince, improving the purity of the garlic mince and the quality of subsequent processing. The garlic mince separated from the impurities is introduced from the bottom of the cyclone separator 25 into the coarse crushing chamber 5. The coarse crushing chamber 5 is equipped with a first filter screen 6 and a rotatable coarse crushing blade 7. The garlic mince falls into the inner side of the first filter screen 6. The coarse crushing blade 7 is connected to the first pulley 20 of a set of drive mechanisms 19 through its shaft end. The first motor 23 at the top of the frame 1 drives the second pulley. 22 rotates, and the second pulley 22 drives the first pulley 20 to rotate via the belt 21, thereby driving the coarse crushing disc 7 to rotate at high speed. Multiple crushing blades 8 are arranged on one side of the coarse crushing disc 7. During rotation, they work in conjunction with the auxiliary striking rods 9 fixed on the first side cover 10 and the coarse crushing disc 7 to perform high-speed cutting, impact, and agitation crushing of the garlic mince, quickly breaking up large lumps and achieving primary crushing, crushing them into particles with a diameter of 2-5 mm. Garlic mince of the qualified size passes through the mesh of the first filter screen 6, exits from the bottom outlet of the coarse crushing chamber 5, and enters the second screw conveyor 33. Large particles that do not meet the standards are intercepted by the first filter screen 6 and continue to participate in the crushing process until they pass through the mesh and fall to the bottom of the coarse crushing chamber 5.The minced garlic is further conveyed upward by the spiral blade conveying shaft 36 driven by the second motor 35 of the second spiral elevator 33, and discharged into the grinding chamber 13 through the discharge port on one side of the top of the lifting cylinder 34 of the second spiral elevator 33. The grinding chamber 13 is equipped with a second filter screen 14 and a rotatable grinding disc 15. The minced garlic falls into the inner side of the second filter screen 14. Several rotating grinding blades 16 are installed on one side of the grinding disc 15. The blades have uniformly arranged grinding teeth and mesh with multiple fixed grinding blades 17 fixed inside the second filter screen 14 to form multiple sets of moving and stationary blade gaps. Driven by the first motor 23 in a set of drive mechanisms 19 connected to the shaft end of the grinding disc 15, the second pulley 22 drives the first pulley 20 to rotate via the belt 21, causing the grinding disc 15 to rotate at high speed. The minced garlic is repeatedly sheared and ground between the rotating grinding blade 16 and the fixed grinding blade 17, crushing it into ultrafine particles. While the material is being fully ground, the closed structure of the chamber and the flow restriction of the second filter screen 14 ensure the uniformity of the final particle size and the processing accuracy. The ground garlic powder is automatically discharged through the discharge pipe 24 at the bottom of the grinding chamber 13 and can be directly used in subsequent processes such as seasoning products, food additives, or drying and storage. Through the above-mentioned coarse crushing-ultrafine grinding equipment that can be operated synchronously, in conjunction with the automatic conveying mechanism between the two, this device can simultaneously perform coarse crushing and ultrafine grinding of minced garlic. This allows the minced garlic to be fully crushed before grinding, and the crushing and grinding are staggered. In the continuous processing of a large number of materials, while one batch of minced garlic is being crushed, the previous batch of minced garlic that has been crushed can be ground at the same time, reducing the grinding time and effectively improving grinding production efficiency and product uniformity. ,
